A UNIQUE TECHNOLOGY FOR PURIFICATION OF DRINKING WATER

Engineer Yordan Velichkov from the town of  Shumen in the North-East of Bulgaria has invented a technology for purification of drinking water. According to his method, the water goes through a system of sieves, which separate the solid particles from the liquid. Engineer Velichkov considers that water purification stations using such technology would cost significantly less in comparison with the existing ones.

The technology developed by engineer Velichkov is based on two stage purification of water. Firstly the water goes through the so called centrifuges, in which as a result of centrifugal forces, the solid particles get separated and then precipitate in hydrocyclones.

Velichkov says that generally hydrocyclones find application in water purification. He explains that he made an improvement by placing additional micro sieves inside the hydrocylcone, which allow the liquid to strain after precipitation.

In his opinion, the new technology has advantages compared to the methods currently applied  for purification of drinking water. He also says that the new technology is three times less expensive, requires less capital investments and implementing it would not lead to rise in the prices of drinking water.

Engineer Velichkov will submit his proposal to the local municipality in Shumen, which plans to announce a tendering procedure for construction of a water purification station.
